FOR IMMEDIATE RELEASE

 

 

7.0 MILLION TONNE TAILINGS RESOURCE ADDS TO WOODLAWN FEASIBILITY STUDY

 

Tri Origin Exploration Ltd (TOE: TSX-V) is pleased to announce that its 51%-owned subsidiary, Tri Origin Minerals Ltd (TRO) has completed a Resource estimate for the Woodlawn Tailing’s Retreatment Project (WRP) West and South tailings dams. The JORC(1) compliant Measured and Indicated Resource is

 

6.98 million tonnes grading 0.55% copper, 1.34% lead, 2.31% zinc, 0.31 grams per tonne gold and 30 grams per tonne silver.

 

An additional Inferred Resource of 1.61 million tonnes at similar grades has also been calculated. The third dam of the WRP, the North tailings dam, is yet to be drilled and evaluated. Based upon historic Woodlawn mine production reconciliations it is anticipated that an additional 2.5 million tonnes of tailings may be defined within this third dam.

 

The Woodlawn Tailings Retreatment Project and Woodlawn Underground Project are being evaluated by TRO on an integrated basis as part of a bankable feasibility study to redevelop the past-producing Woodlawn mine. This study is on schedule for completion during the first quarter of 2008. Statutory approvals are being run in parallel with the study and are on schedule for completion by mid 2008.

 

The tailing resources (Tables 1, 2 and 3) for the West and South tailings dams have been independently estimated by Mr Robin Rankin of GeoRes (GeoRes), Sydney, Australia.

The Woodlawn property located 200 kilometres southwest of Sydney, New South Wales was acquired by Tri Origin in 1999 and was considered a key asset of the Company during the ASX listing of its subsidiary in 2004. The Woodlawn mine operated from 1978 to1998 milling approximately 13.8 million tonnes of high grade ore from open pit and underground operations. The operations closed due to prevailing low metal prices and corporate reasons.

 

In October last year TRO released a Measured and Indicated Resource estimate for the underground component of the Woodlawn Zinc project of 8.58 million tonnes grading 1.8% copper, 4.0% lead, 10.3% zinc, 0.54 grams per tonne gold and 84 grams per tonne silver. Based on this resource, a pre-feasibility evaluation of the underground component of the Woodlawn Zinc project was subsequently completed with positive results. TRO is now progressing a bankable feasibility study for Woodlawn and the new tailings resource estimate will be integrated into that study. The combined Measured and Indicated Resource for the property now stands at 15.6 million tonnes. This will be the first economic evaluation of an integrated underground and tailings retreatment operation.

 

A positive economic evaluation from the bankable feasibility study would likely result in a tailings retreatment project in the order of 1.5 million tonnes per annum and an underground operation producing 440,000 tonnes per annum. In effect TRO is pursuing the development of a near 2 million tonnes per annum operation at Woodlawn. The advantage of an integrated project would be the potential to blend a low grade concentrate from the tailings with that of higher grade concentrate produced from underground ore and the potential benefit of operating economies of scale given the combined tonnage throughput. The overall potential of the Woodlawn Zinc Project is to produce 120,000 to 130,000 tonnes per annum of concentrates at the site.

 

The capital requirements for this project will be determined by the bankable feasibility study. It is now estimated by TRO that capital costs may be in the order of $150 million.

 

Tailings Resources have been estimated by GeoRes using a validated database comprising data from 88 drill holes and survey data of dam and tailings surfaces. The significant percentage of Resources in the Measured (45%) and Indicated (36%) categories at both the West and South tailings dams (Tables 2 and 3) is a function of reliable geostatistical characteristics resulting from high data density. This, combined with conservative extrapolation parameters explains the relatively small percentage of Inferred Resources. Additional drilling in the future, including the north dam, would further increase the confidence of contained metal within the dams. Where historical operating records from the Woodlawn Mine were available these were reconciled with dam volumes and grades. These reconciled within the confidence levels of the Resource estimates. TRO considers that the existing definition is sufficient to complete an economic evaluation for the bankable feasibility study.
